1st Dyno run

Postby DLittle » Sat Mar 03, 2007 11:03 pm

I finally got to dyno my truck. I was hoping for 300hp/650 tq. I got the 300 actually 301hp. I knew my troque would be hard to hit with a stock super slip auto but I didn't think this much.I had 538.2 on torque.

My question to everyone that has dyno'd is look at where my max torque is in the rpm scale is it so high because of the auto ? Also I hit peak HP at 3300rpm ?

I guess I had better do some tranny work :D

Looks like the truck is running great at high RPM! I wish my curves looked like that. :x

Were they using a crank moumted rpm pickup? Why did they start the runs at 2000rpm? I think had they to have started at 1400-1500 you would have seen alot better torque numbers.
